When Metamodel is created based on hbm xml file mapping then wrong entity name is set for {{MetamodelImpl#entityPersisterMap}} comparing with annotation based one.
Because of that it is impossible to get entity persister by its class for any entity that has configred entity-name in hbm xml file.
After all this one leads to nasty:
{code:java}
java.lang.IllegalArgumentException: Not an entity [class net . avaleo . business . domain.patient.Patient ]
at org.hibernate.internal.SessionImpl.contains(SessionImpl.java:2140)
{code}
After deep debugging we found that in {{org.hibernate.boot.model.source.internal.hbm.ModelBinder}} which is responsible for creation of bindings based on hbm xml files {{entity-name}} xml attribute is assigned to {{PersistenceClass#entityName}} class mapping:
{code:java}
private void bindBasicEntityValues(
MappingDocument sourceDocument,
AbstractEntitySourceImpl entitySource,
PersistentClass pc) {
pc.setEntityName( entitySource.getEntityNamingSource().getEntityName() );
pc.setJpaEntityName( entitySource.getEntityNamingSource().getJpaEntityName() );
pc.setClassName( entitySource.getEntityNamingSource().getClassName() );
[...]
{code}
in opposite to {{org.hibernate.cfg.annotations.EntityBinder}} where a class name is assigned to {{PersistenceClass#entityName}}
{code:java}
public void bindEntity() {
pc.setEntityName( annotatedClass.getName() );
pc.setClassName( annotatedClass.getName() );
pc.setJpaEntityName(name);
{code}
